This investigation is one ofa series ofbroad biological resource studies which have been conducted in the Region, including within Nullica State Forest immediately to the east (Binns and Kavanagh, 1990a), and in several areas to the west ofthe Jingo Creek study area - the Myanba Creek (Fanning and Mills, 1990a), upper Wog Wog River (Fanning and Fatchen, 1990), and Stockyard Creek catchments (Fanning and Mills, 1991) in Coolangubra State Forest, as well as part ofNalbaugh State Forest (Binns and Kavanagh, 1990b). These studies were designed to assess the "conservation value of certain habitats and species" within the catchments using a 'broad brush' ecosystem approach. Nullica State Forest, like the other areas investigated, is part ofthe Eden Woodchip Agreement Area. The forests within this management area are to be logged using integrated harvesting practices to supply both sawlogs for timber mills in the Region and material for the production ofwoodchips for export from Eden. The Forestry Commission ofNew South Wales has devised a detailed management plan for the forests in the Region, involving division ofthose portions ofthe forest which are to be logged into coupes which are harvested on an alternate basis over a 40+ year cycle, and the reservation ofsignificant areas offorest (for a variety ofreasons). Specific areas are reserved for conservation purposes, and management prescriptions apply within each coupe being logged to provide for the wildlife ofthe Region. Details ofthe management practices, including the alternate coupe system, integrated

  • Morphological Variation Within the Genus Blandfordia (Liliaceae) in Relation to Its Environment
    21 August 1992 Aust. Syst. Bot., 5, 373-85 Morphological Variation Within the Genus Blandfordia (Liliaceae) in Relation to Its Environment Carolyn L. PorterAB, David A. MorrisonA and Kristina A. JohnsonA *Department of Applied Biology, University of Technology Sydney, PO Box 123, Broadway, N.S.W. 2007, Australia. BCurrent address: National Herbarium of N.S.W., Mrs Macquarie's Road, Sydney, N.S.W. 2000, Australia. Abstract The taxa in Blandfordia are often difficult to separate morphologically. A multivariate morphometric analysis of data from both herbarium and field samples suggests that the genus consists of at least four polythetically distinct taxa, corresponding to the traditional concepts of B. cunninghamii Lindley, B. grandifora R.Br., B. nobilis Smith, and B. punicea (Labill.) Sweet. The morphological boundaries between most of these species are arbitrary but are closely related to a number of environmental variables. Due to large intra-population variability, discrimination between these taxa is possible only on the basis of a combination of attributes, notably leaf width and margin sculpturing, and flower length and diameter. The morphological distinction between B. punicea and the other species is clear and seems to be maintained by its geographical isolation. The distinction between B. grandiflora and B. cunninghamii is based on vegetative rather than floral attributes and is made difficult by phenotypic response of B. cunninghamii plants to light intensity. Gene flow between these two species appears to be restricted by their separate habitats. The distinction between B. grandiflora and B. nobilis is based on floral rather than vegetative attributes and is related to latitude with the species being more distinct in the area of parapatry than in the area of allopatry.

Email: [email protected] Abstract: The Southern Forests study area covers an area of about six million hectares of south-eastern New South Wales, south of Oberon and Kiama and east of Albury and Boorowa (latitude 33° 02’–37 ° 06’ S; longitude 146° 56’ – 147° 06’ E). The total area of existing vegetation mapped was three million hectares (3 120 400 hectares) or about 50% of the study area. Terrestrial, wetland and estuarine vegetation of the Southern Forests region were classified into 206 vegetation groups and mapped at a scale between 1: 25 000 and 1: 100 000. The classification was based on a cluster analysis of detailed field surveys of vascular plants, as well as field knowledge in the absence of field survey data. The primary classification was based on 3740 vegetation samples with full floristics cover abundance data. Additional classifications of full floristics presence-absence and tree canopy data were carried out to guide mapping in areas with few full floristic samples. The mapping of extant vegetation was carried out by tagging vegetation polygons with vegetation codes, guided by expert knowledge, using field survey data classified into vegetation groups, remote sensing, and other environmental spatial data.

  • Rare Or Threatened Vascular Plant Species of Wollemi National Park, Central Eastern New South Wales
    Rare or threatened vascular plant species of Wollemi National Park, central eastern New South Wales. Stephen A.J. Bell Eastcoast Flora Survey PO Box 216 Kotara Fair, NSW 2289, AUSTRALIA Abstract: Wollemi National Park (c. 32o 20’– 33o 30’S, 150o– 151oE), approximately 100 km north-west of Sydney, conserves over 500 000 ha of the Triassic sandstone environments of the Central Coast and Tablelands of New South Wales, and occupies approximately 25% of the Sydney Basin biogeographical region. 94 taxa of conservation significance have been recorded and Wollemi is recognised as an important reservoir of rare and uncommon plant taxa, conserving more than 20% of all listed threatened species for the Central Coast, Central Tablelands and Central Western Slopes botanical divisions. For a land area occupying only 0.05% of these divisions, Wollemi is of paramount importance in regional conservation. Surveys within Wollemi National Park over the last decade have recorded several new populations of significant vascular plant species, including some sizeable range extensions. This paper summarises the current status of all rare or threatened taxa, describes habitat and associated species for many of these and proposes IUCN (2001) codes for all, as well as suggesting revisions to current conservation risk codes for some species. For Wollemi National Park 37 species are currently listed as Endangered (15 species) or Vulnerable (22 species) under the New South Wales Threatened Species Conservation Act 1995. An additional 50 species are currently listed as nationally rare under the Briggs and Leigh (1996) classification, or have been suggested as such by various workers. Seven species are awaiting further taxonomic investigation, including Eucalyptus sp.

The stand was thinned at age 26 years , reducing the basal area by ca. 50% and lowering the stocking from ca. 1350 to ca. 250 stems ha1. Whereas the species diversity and richness of the understorey were not signi®cantly affected by the treatments, thinning promoted the abundance of herbaceous species, and fertilisation increased the proportion of ground ferns such as Pteridium esculentum. Fertilisation with 100 kg N ha1 and 100 kg P ha1 decreased the foliage N concentration in Tetrarrhena juncea and Gonocarpus teucrioides, and increased the foliage P concentrations in four of the ®ve most frequent species. This suggested that the understorey was more limited by P than by N. The photosynthetically active radiation above the understorey was 41% of that in the open in thinned stands and 32±34% in unthinned stands, showing that 6 years after thinning the canopy density had not yet returned to pre-treatment levels.
